Much better, it makes the main page seem far less cluttered and busy. I know it is just for E3, but consider keeping it year round, or at least making the background brighter than the last one.
This! A simple change like this and I'm in love with the home page outside of the performance issues on my old POS. If I had a vote, I'd say keep the background as is and change the header whenever the situation calls for it(E3, game releases, contets, etc.)
